PEEBLES SAFETY'GLAMP Filed Sept. 6, 1959 3 Sheets-Sheet 3 Patented Mar. 18, 1941 mm" earns PATENT OFFICE My invention relates generally to improvements in clamps and reenforcement strip apparatus and it consists in the combination, construction and arrangements, herein described, and claimed.

It is an object of my invention, to provide a strong, durable and efiicient safety clamp, adaptable to hold securely and safely the head of a tool, such as a hammer, axe, mall, hatchet or like object to the handle of such tool, reenforcing the said handle against breaking at or near the head and to generally improve upon and simplify the construction of the existing type of clamps and to provide a construction that is relatively simple, capable of being easily and cheaply produced.

Embodied in the foregoing device, are several distinct inventions which are dependent upon each other and which. mutually contribute to produce the aforesaid device. The reenforcement and clamping meansfor securing the said device to the handle of the tool, as separately claimed are readily adaptable as a strong, durable and eflicient clamping and reenforcement means for use on hose, cable, pipes, broken parts of furniture, hardware, tools, implements, and a clamping and reenforcement means which are adaptable in tree grafting and for the setting of broken bones.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the embodiment of my invention illustrated in Figures 10 and 11, my improved safety clamp is stamped from sheet metal in one piece in the form of a blank. The blank for the clamping -'means is shown'in detail in Figure 4. Formed integral with the clamping means along the line 2, of Figure 4, there is provided a band or sheet metal strap 4, Figures 10 and 11, which is suitably bent at 19, 80, 8|, 82, 83 and 84, so as to fit around the head of the desired tool, as shown in Figure 11, and the said metal strap i formed integral with the reenforcement strip 9, along the dotted line 10, the detailed structure of the blank for the said reenforcement strip is shown in Figure 9.

The aforesaid clamping means comprises preferably four bands or lateral extensions indicated by numerals ll, l2, l3 and I4, Figures 1, 4 10 and 11, formed integral with a reenforcement strip or connecting tie l5, extending at right angles to the said bands. The said bands H, l2, l3 and I4, are formed with a longitudinal slot therein indicated respectively by numerals l6, l|-, l8 and IS, the purpose of which will appear hereafter. The bands H, and I3, and the bands l2, and H, are shaped from the blank, Figure 4, into two separate circular collars, having the end parts thereof, projecting radially outward to serve as clamping ears or flanges. The reenforcement strip l5, of the sheet metal strap 4, is bent or transversely curved along the periphery of the said circular collars. The metal strap 4, being formed integral with the clamping means 'along the line 2, and curved further as shown in Figures 10 and 11, to fit the handle of the tool and turned at '19, 80, 8|, 82, 83 and 84, to fit the head of the tool, Figures 10 and 11. The further end of the said sheet metal strap 4, being curved to fit the opposite side of the handle of the tool is formed integral with the reenforcement strip 9.

The flange 20, of the band I3, Figure 4, is bent, along the dotted line 2I, substantially at right angles to the said band, and the end part 22, of the band I3, is bent, along the dotted line 23, over, parallel and contiguous with the flange 26, thereby serving as a support to the projecting car 20, as shown in Figures 2 and 3.

The flange 24, of the band I4, is bent, along the dotted line 25, similar to flange 20, and the end part 26, of the band I4, is bent, along the dotted line 21, parallel and touching the flange 24.

The flange 28, of band II, Figure 4, is bent substantially at right angles to the said band, along the dotted line 29, and the end part 30, is bent along the dotted line 3I, at right angles to the flange 28, forming an outwardly bent lip, as shown in Figures 2 and 11, and the flange 32, of the band I2, is bent along the dotted line 33, substantially at right angles to the band I2, and the end part 34, of the band I2, is bent along the dotted line 35, at right angles to flange 32, in a similar manner to end part 36, of band II, as shown in Figure 11.

The radially projecting parts 20, 22 and 28, have provided, therein, a bolt hole indicated, respectively, by numerals 36, 31 and 38, for the reception of a clamping bolt 39, having a screw threaded shank, which engages the nut 40, by means of which the said bands II and I3, are tightened. The outwardly bent lip 30, on the projecting ear 28, is so constructed as to restrain the nut 40, from turning with the bolt 39, as shown by Figures 2 and 11.

The radially projecting parts 24, 26 and 32, have similarly provided, therein a bolt hole indicated, respectively, by numerals 4|, 42 and 43,

for the reception of clamping bolt 44, engaging the nut 45, by means of which the bands I2 and M, are tightened. The said nut 45, is restrained from turning with the bolt 44, by the outwardly bent lip 34, as shown by Figure 11.

There is further provided an additional reenforcement strip 9, formed integral with the sheet metal strap 4, along the line I0, and the said reenforcement strip 9, is stamped in the form of a blank, having cuts in the edges, thereof, as shown in Figure 9, so as to form the parts 46, 41, 48 and 49, which parts are bent outward along the dotted lines 50, 5|, 52 and 53, respectively, and around upon the reenforcement strip 9, forming looped members.

The said reenforcement strip 9, is bent or curved transversely along the periphery of the circular collar formed by the bands II and I3, and the circular collar formed by the bands I2 and I4.

The said reenforcement strip 9, is adapted to be inserted between the object to which the clamp is to be applied and the inner sides of the said bands, directly opposite the reenforcement strip I 5, extending across the space between the clamping ears 24 and 32, and across the space between the clamping ears 2 and 11.

The loopedmembers formed by theparts 46, 41, 48 and 49, are inserted from the inner side of the respective bands II, I2, I3 and I4 into the respective slots I6, I1, I8 andI'9. The said slots are adapted for the respective looped members to move longitudinally therein and as the clamping bolts 39, and 44, are tightened on the respective nuts 40 and 45, thereby tending to close the ends of the circular collars, the looped members, aforementioned, containedin therespec- 20 and 28, as shown by Figurestive longitudinal slots, move therein toward the reenforcement strip I5, thus clamping and reenforcing the handle of the tool and holding securely the head of the tool.

In the embodiment of my invention illustrated in Figure 14, there is shown a modified specie of my invention which is stamped from sheet metal in three pieces in the form of blanks. The same differs from the specie shown in Figure 10, in that instead of having the bands or lateral extensions I3 and I4, formed integral with the reenforcement strip I5, there is formed integral with the reenforcement strip I 5, and at right angles thereto, the flanges 54, and 55, respectively, apertured at 56, and 51, as shown by Figures 5 and 8, to receive respectively the tongue 59, of the hinged band or lateral extension indicated by numeral 56. The hinged band or lateral extension 58, is stamped from sheet metal in the form of a blank as shown in Figure 7, having a tongue 59, which is adapted to be inserted from the inner side of the flange 54, through the aperture 56, and bent around the part 60, upon the hinged band 58,

and thesaid tongue 59, likewise is adapted to be inserted from the inner side of the flange 55, through the aperture 51, and bent around the part 6 I, upon the hinged band-58.

The bands or lateral extensions II and I2, Figure 8, are formed substantially as previously described. The hinged bands 58, are shaped with the band II, and band I2, from the blanks, Figures 7 and 8, into two separate circular collars, Figures 5 and 6, having the end parts thereof, projecting radially outward to serve as clamping ears or flanges. The flange 62, of the hinged band 58, Figure 7, is bent along the dotted line 63, substantially at right angles to the said band, and the end part 64, of the hinged band 58, is bent, along the dotted line 65, over, parallel and contiguous with the flange 62.

The projecting parts 62 and 64, have provided therein a bolt hole indicated by numerals 66 and 61, respectively, adapted for the reception of the clamping bolt 39, which is further received in the bolt hole 38, of band II, and engages the nut 40, by means of which the said bands II' and 58, are tightened, Figures 5 and 6. The bolt holes 66 and 61, are similarly adapted for the reception of the clamping bolt 44, which is further received in the bolthole 43, of band I2, and engages the nut 45, by means of which the said bands I2 and 5 are tightened.

The hinged band 58, is formed witha longitudinal slot 68, therein. The said slot 68, of hinged band 58, like slot I8, of band I3, previously explained, is adapted with the longitudinal slot I6, of band II, for the looped members 48 and 46, of the, reenforcement strip 9, to move, respectively, longitudinally therein, and the said slot 68, like the slot I9, of band I4, previously explained, is adapted with the longitudinal slot I1, of band I2 for the looped members 49 and 41, of the reenforcement strip 9, to

, transversely along the periphery of the circular collar formed by the bands II and 58, and the move, respectively, longitudinally therein, as shown by Figures circular collar formed by the bands I2 and 58, I

and as the said collars are tightened by the clamping bolts 39 and 44, respectively, the said reenforcement strip 9, is further transversely curved and the looped members, aforementioned,

contained in the respective longitudinal slots,

move therein toward the reenforcement strip I5,

thereby clamping and reenforcing the handle of the tool and holding the head of the tool securely thereto. 1 1

The clamping means described above is formed integral at line 2, with a sheet metal strap 4, which is formed substantially as previously described, the further end of the said sheet metal shaped .to form a circular collar having the, end

parts, thereof, projecting radially outward to serve as clamping ears or flanges, as previously described. The metal strap 5, is bent or transversely curved along the periphery of the said circular collar and curved to fit the handle of the tool and turned at l and 8, Figure 12, to fit the head of the tool as shown in Figure 13. In order to give further support to the head of the tool the upper edge 89, and the lower edgelll, of the side of the sheet metal strap 5, are stamped substantially convex, Figure 13, and the further side of the said metal strap is formed substantially the same. The further side of the metal strap 5, aforesaid, being curved to flt the handle of the tool, is formed integral with a reenforcement strip II. The said reenforcement strip H, of sheet metal strap 5, having cuts in the edges thereof, forming on the opposite edges, thereof,

parts 12 and 13, formed substantially the same as parts 46 and 48, shown in Figure 9, and previously described. The said parts l2 and [3, are bent outwardly and around upon the reenforcement stripll, forming looped members.

The said reenforcement strip H, is bent or curbed transversely along the periphery of the circular collar formed by the bands II and I3. The said reenforcement strip H, is adapted to be inserted between the object or handle'of the tool to which the clamp or collar is to be applied; and the inner sides of the said bands, directly opposite the other side of the sheet metal strap 5, extending across the space between the clamping ears 20 and 28, of bands and I3, respectively.

The looped members l2 and I3, are inserted from the inner sides of the said bands. II and 53, respectively, into the respective, longitudinal slots l5 and l8,of bands II and I3.

The said looped members I2 and i3, correspond respectively, to the looped members 46 and 48, as shown in Figures 2 and 3. The said slots are adapted for the respective looped members 12 and I3, to move longitudinally therein, as the clamping bolt 39, is tightened on the nut 40, as shown in Figures 12 and 13, thereby, tending to close the ends of the circular collar formed by the bands I! and I3, and causing the looped members I2 and 13, to move longitudinally, therein, clamping and reenforcing the handle of the tool and securing the head, thereof, safely in place. i
